The available energy ea when the proton and the antiproton have equal energies of 450gev is 29 GeV.
How to find the available energy after the collision?The available energy can be found out with the following formula.
[tex]E_a=\sqrt{2E_tE_k++(m_1c^2)^2+(m_2c^2)^2}[/tex]
Here C is the speed of light (3×10⁸ m/s), Et is the energy of proton, Ek is the rest energy.
A proton and an antiproton have equal energies of 450gev. The particles collide head-on. The rest energy of the proton is 938mev
Thus, put the given values in the above formula,
[tex]E_a=\sqrt{2(450\times\dfrac{10^9eV}{1MeV})(938\times\dfrac{10^6eV}{1MeV})+(938\times\dfrac{10^6eV}{1MeV})^2+(938\times\dfrac{10^6eV}{1MeV})}\\E_a=29\rm\; Gev[/tex]
Thus, the available energy ea when the proton and the antiproton have equal energies of 450gev is 29 GeV.

Why is the moon’s force of gravity less than that of the earth?
Why is the moon’s force of gravity less than that of the earth?
Answer:-Since the moon has a smaller mass than the earth, the moon has less gravity than the earth. Gravity is related to mass.
Larger mass = larger gravity
Smaller mass = lesser gravity
Moon has small mass, therefore less gravity.

Angular frequency in radian per second for 20 vibrations in 10 seconds is 12.6 rad/s
What is Angular frequency?Angular frequency is the number of vibrations in radian per second.
The total number of vibrations n is 20 and the time taken for these vibrations is 10 s
The frequency of the vibrations will be
f = 20 / 10 = 2 Hz

A circular loop has a radius of .3 meters a magnetic field has an initial strength of 2 tesla directed out of the page. over the course of 5 seconds the magnetic field is changed to 3 tesla directed out of the page calculate the induced voltage in the loop
Hi there!
We can use Faraday's Law to solve:
[tex]\epsilon = N\frac{d\Phi _B}{dt}[/tex]
ε = Induced emf (? V)
N = Number of loops (1 loop)
ΦB = Magnetic flux (Wb)
We know that:
[tex]\Phi_B = \oint B \cdot dA = B\cdot A[/tex]
Since the area of the loop remains the same, we can take this out of the time derivative.
We get:
[tex]\frac{d\Phi_B}{dt} = A * \frac{dB}{dt}[/tex]
Also, since N = 1, we can now rewrite the equation for the induced emf as:
[tex]\epsilon = A * \frac{dB}{dt}[/tex]
dB/dt is equivalent to the change in the magnetic field with respect to time:
[tex]\Delta B = \frac{B_f - B_i}{\Delta t}\\\\\Delta B = \frac{3 - 2}{5} = 0.2 \frac{T}{s}[/tex]
Now, substitute this value into the equation for induced emf:
[tex]\epsilon = \pi (0.3^2) * (0.2) = \boxed{0.0565 V}[/tex]
**Also, since the magnetic field INCREASED out of the page, this change in magnetic flux will create an induced CLOCKWISE current that produces a magnetic field into the page in order to oppose the increase in magnetic flux OUT of the page.

How much heat energy is required to raise the temperature of 1 kilogram of steel by 10°C?
from
∆H=MC∆T
but M=1Kg=1000g
∆T=10°C
C=0.466J/g°C
∆H=(1000×0.466×10)Joule
=4660J
explanation
When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.
heat energy = (mass of substance)(specific heat)(change in temperature)
Q = mc∆T
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)
∆ is a symbol meaning "the change in"

What is resonance frequency?Mechanical systems and charged particles all have a frequency that they vibrate at. this frequency is referred to as the resonance frequency or natural frequency.
When the matching vibrations of another item enhance the amplitude of an object's oscillations, this is known as resonance.
15 Hz is the fundamental frequency of the string.
Higher frequencies, such as the first overtone, second overtone, third overtone, and so on, must be used to cause the string to vibrate in a resonant manner.
F₁ = 2F₀ = 2 x 15 = 30 Hz is the initial overtone.
F₂ = 3F₀ = 3 x 15 = 45 Hz is the second overtone.
F₃ = 4F₀ = 4 × 15 = 60 Hz is the third overtone.
